The LM4781 is a three channel audio amplifier capable of typically delivering 35W per channel of continuous average output power into an 8? load with less than 0.5% THD+N from 20Hz – 20kHz. The LM4781 is fully protected utilizing TI"s Self Peak Instantaneous Temperature (°Ke) (SPiKe) protection circuitry. SPiKe provides a dynamically optimized Safe Operating Area (SOA). SPiKe protection completely safeguards the LM4781"s outputs against over-voltage, under-voltage, overloads, shorts to the supplies or GND, thermal runaway and instantaneous temperature peaks. The advanced protection features of the LM4781 places it in a class above discrete and hybrid amplifiers.Each amplifier of the LM4781 has an independent smooth transition fade-in/out mute. The LM4781 can easily be configured for bridge or parallel operation for higher power and bi-amp solutions.
